【摘要】 建立一个适合于特定说话人识别系统的汉语语音数据库,对推动说话人识别技术的研究和应用具有重要意义。本文针对说话人识别中信道差异问题,设计并建立了跨信道说话人识别语音库XMU-Multi Channel。本文首先分析比较了国内外现有的说话人识别语音库,设计了跨信道说话人识别语音库的语料内容、采集系统、录音方案以及标注和存储方式,进一步基于这个数据库实现了PLDA参数更新的跨域迁移策略,以解决小样本信道PLDA建模的困难,并在语音样本有限的前提下提高了说话人识别系统的识别性能。更多还原

【Abstract】 The establishment of a Chinese speech database has a great significance in promoting the research and application of speaker recognition technology. This paper designs a cross-channel speech database XMU-Multi Channel for the research of channel mismatch in speaker recognition. After comparison of existing domestic and international speaker recognition speech database, this paper has a discussion on recording program, acquisition system, recording content, labeling and storage. Based on our designed XMU-Multi Channel database, a cross-domain transfer strategy experiment of PLDA was implemented. As a result, the difficulties for small samples to train the PLDA model could be resolved.更多还原
